§7 M3 wrapped the three plan request bodies in a `{bundle, project}` struct,
silently breaking version-skew compatibility: a pre-§7 `pic plan` POSTs a BARE
bundle at the JSON top level and now fails deserialization (422 "missing field
bundle"), even though the sibling apply request deliberately kept its added
fields additive (`#[serde(default)]`) so an older CLI still works.
`#[serde(flatten)]` the bundle in `PlanRequest`/`TreePlanRequest` so the bundle
fields sit at the top level again: a bare bundle deserializes (`project`
defaults to `None`) and a newer client sends the same fields plus a top-level
`project` key. The CLI now builds that shape via a `plan_body` helper (bundle
object + optional `project`), which an older server also accepts (Bundle has no
`deny_unknown_fields`, so the extra key is ignored) — compatible in both skew
directions. Apply is left unwrapped (it was already `{bundle, ...}` pre-§7).
Pinned by `plan_request_accepts_a_bare_bundle` / `_a_flattened_project` /
`tree_plan_request_accepts_a_bare_bundle` unit tests.

PiCloud
A lightweight, self-hosted, event-driven serverless compute platform. Upload a Rhai script, get an HTTP endpoint. Designed to run on a single modest server with no idle CPU cost, and to scale out to a small cluster when you need it.
Status: Phase 1 — MVP scaffolding in progress.
The authoritative design lives in
serverless_cloud_blueprint.md.
Why
Existing serverless platforms are either cloud-locked, heavyweight, or both. PiCloud aims for the opposite end of the spectrum: one binary, one database, one reverse proxy — running on hardware you already own.
Architecture (one paragraph)
PiCloud splits into three logical services — manager (control plane: scripts, schedules, dashboard), orchestrator (per-node event ingress and dispatch), and executor (per-node Rhai sandbox) — each backed by a *-core Rust library. In MVP they run in a single process; in cluster mode they run as three binaries with one manager and one orchestrator + executor per node. Caddy fronts everything; PostgreSQL is the single source of truth.
See CLAUDE.md for working notes and serverless_cloud_blueprint.md for the full design.
Quick Start
Coming as scaffolding lands. For now:
# Rust toolchain (pinned via rust-toolchain.toml)
cargo check --workspace
# Run the all-in-one MVP binary (once main.rs is wired up)
cargo run -p picloud
